Table 2

Scores and parameters evaluated on Noncontrast Computed Tomography (NCCT), Computed Tomography Angiography (CTA), and Computed Tomography Perfusion (CTP).

NCCT	CTA	CTP
(i) ASPECTS, stratified ≤7 and >7; (ii) Leukoaraiosis, stratified as “present” or “absent”; (iii) Clot Length, divided >10mm or <10mm; (iv) Clot Density (Hounsfield Units) corrected by contralateral density: Clot density ratio; (v) Site of Occlusion	(i) Clot Burden Score (CBS), stratified ≥6 and <6; (ii) Collaterals as Pial Arterial Filling Score (PAF) within the affected territory Using Single and Multiphase CT Angiography. Stratified in >4 and ≤4	(i) Ischemic Core Volume, Penumbra Volume using the ABC/2 formula; (ii) Mismatch between Mean Transit Time (MTT) and Cerebral Blood Volume (CBV); (iii) CBV ASPECT, then stratified in >8 and ≤8
